JOHN P. LEIN, OF NEW YORK, N. Y.

BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 746,852, dated December 15, 1903. Application iiled November 1'7, 1902. Serial No. 13151?. (No model.)

To all whom it may concern:

Beit known that I, JOHN P. LEIN, agcitizen of the United States, residing at New York, inthe county of New York and State of New York, have invented certain new and useful the bed or to have the bed inclined or to raise the patient higher, so as to obviate the necessity of bending over to attend to him.

With these objects in view I have devised the construction which I will now more particularly describe.

In the drawings, Figure 1 is a side view of one end vof a bed, showing the mattress-frame elevated. Fig. 2 is an end view of a bed-frame provided with my invention. Fig. 3 is a de tail side elevation of a mattress-frame. Fig. 4 is a detail view of an end post of a bed, showing the rack supporting the corner of the mattress-frame; and Fig. 7 shows a rack out in the bed-post. Fig. 5 is a plan, seen from below, of the frame shown in Fig.. 3. Fig. 6 is a modication of Fig. 5.

I provide each of the four posts l of a bed with racks 2. Fig. 2 shows the arrangement and location of the racks on one end ofthe bed, the arrangement forthe other end being the same.

The mattress-frame is composed of anglebars 3 4 and carries the Woven-Wire springs 8 in the usual manner. As ordinarily made this frame cannot be adjusted to different heights, nor can it be removed Without great difficulty. Pivote'd near each corner of the frame on the side bars are levers 6, normally pushed outward by springs 7. The levers may be provided with suitable stops, as 12, to prevent them from moving out too far. By this construction the lever forms a rigid hang die when pushed outward by binding against the angle-bar 4. The pivots 9 of the levers are in slots l0, so that the levers can be moved bodily longitudinally of the side toward each other to permit them to clear the top bars of the end frames of the bedstead when it is desired to remove ,the mattress-frame entirely. It will thus be seen that I am enabled to use the mattress-frame as a stretcher, which is `found to be of great convenience in hospitals, the levers 6 serving as handles. The racks 2 enable the frame to Abe adjusted to various heights and alsopermit one end to be at a different height frorn the other..

When itis desired to change the position of the mattress-frame, an attendant at each end of the ybed grasps the two levers of the frame at each end and presses them inward toward each other and then adjusts the mattress-frame as desired. The springs push the levers outward and cause them to engage the racks to sustain the mattress-frame.

In Fig. 6 is shown a modified construction which enables the tension of the spring to be regulated. 14 is a bolt having a head l5 and a nut 16. 13v is a coiled spring which bears at one end on the head 15 and at the other on an eyebolt 17, which is adjustable in the slot 16 to vary the tension of the spring. This can also be eected by screwing the nut 18.

' Ido not limit myself to the construction I have illustrated, as my invention can be applied to many other constructions by a skilled mechanic.

Having thus described my invention, I declare that what I claim as new, and desire to secure by Letters Patent, is

I. The combination with a bed-frame having notches, of a mattress-frame having a lever independently V`pivoted near each corner thereof and engaging the notches to support 'the mattress-frame at any desired height or angle, substantially as described.

2. The combination with a bed-frame, of a mattress-frame having levers slidably mounted near the corners thereof, and means for holding the levers in engagement with the bed-frame to support the mattress-frame, substantially as described.

Y3. In a bed, a mattress-frame having a lever mounted on the side hars near each end thereof, means for holding the levers in engagement with the bed-frame, and means permitting the levers to be moved longitudinally so as to clear the ends of the bed-frame.

4. In a bed, the combination with the corner-posts having each a rack thereon, of a controlled supporting means independently attached near each corner thereof and engaging the supporting means on the bed-frame, to permit the ends or sides of the mattressframe to be independently adjusted to any desired height or angle, substantially as described.

In testimony Whereof I affix my signature in presence of two Witnesses.
